[0043] The following further details the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0044] The present utility model first relates to a strong gathering spinning component, which can be applied to an existing spinning machine, connected to the dust suction air duct of the existing spinning machine, generate negative pressure inside, and thus realize two functions of yarn gathering and dust suction.

[0045] The overall structure of the strong gathering spinning component of the present utility model is as shown in Figure 1 , Figure 2 , Figure 3 , and the internal partial structure is as shown in Figure 4 , Figure 5 , including a butt joint air duct 1, a cavity 2, a yarn gathering air cavity 3, a yarn gathering support 4, a mesh belt 5, a support 6, and a dust suction nozzle 7;

[0046] The butt joint air duct 1 is connected to the dust suction air duct of the spinning machine to generate a negative pressure of appropriate size inside the strong gathering spinning component of the present utility model. The butt joint air duct 1 is connected to the cavity 2, so that a negative pressure is also generated inside the cavity 2.

[0047] The cavity 2 is connected to the yarn gathering air cavity 3, so that a negative pressure is generated inside the yarn gathering air cavity 3; both sides of the cavity 2 extend outwards to form the dust suction nozzle 7.

[0048] Both sides of the yarn gathering air cavity 3 are respectively connected with a yarn gathering support 4; two yarn gathering supports 4 are respectively sleeved with a mesh belt 5, and one dust suction nozzle 7 is arranged outside each mesh belt 5.

[0049] Preferably, a support 6 is further arranged at the bottom of the yarn gathering support 4, and the support 6 is fixed on both sides of the cavity 2; the bottom of the support 6 is an arc surface; further, the support 6 is a horizontally arranged cylinder; the support 6 is used to provide support for the bottom of the mesh belt 5.

[0050] The top of the yarn gathering support 4 is a plane, and a yarn gathering suction nozzle 41 is arranged in the middle of the plane; the inside of the yarn gathering support 4 is a negative pressure cavity 42, and the negative pressure cavity 42 is connected to the yarn gathering air cavity 3, that is, a negative pressure is generated inside the negative pressure cavity 42; the yarn gathering suction nozzle 41 is communicated with the negative pressure cavity 42, that is, sufficient adsorption force is generated near the yarn gathering suction nozzle 41 to gather yarn.

[0051] Further, the side of the yarn gathering nozzle 41 close to the yarn inlet is a triangular nozzle 411, and the side close to the yarn outlet is a narrow strip nozzle 412; the triangular nozzle 411 and the narrow strip nozzle 412 are in communication, so that the adsorption area of the yarn gathering nozzle 41 is larger on the side close to the yarn inlet and gradually becomes smaller in the direction of the yarn outlet. Thus, under the adsorption of the yarn gathering nozzle 41, the yarns first gather and then further converge inward during the process of moving forward along the yarn gathering nozzle 41.

[0052] Further, the top of the yarn gathering support 4 of the spinning machine is a replaceable wear-resistant plate 43, and the opening part of the yarn gathering nozzle 41 is located on the wear-resistant plate 43. Since the yarn gathering support 4 of the spinning machine supports the mesh belt 5 and the mesh belt 5 moves during operation, thus rubbing the top of the yarn gathering support 4 of the spinning machine, the replaceable wear-resistant plate 43 is adopted. On the one hand, the durability of this part is improved and the service life is prolonged. On the other hand, it can be replaced separately when the wear is serious.

[0053] At the same time, the shape, position, size, etc. of the opening of the yarn gathering nozzle 41 on the wear-resistant plate 43 can be changed according to the fibers to be spun, adjusted quickly, and the adjustment cost is low.

[0054] Further, the top of the yarn gathering support 4 of the spinning machine is lower than the yarn gathering air cavity 3, so that the inner side of the mesh belt 5 will be limited by the side of the yarn gathering air cavity 3.

[0055] Furthermore, the outer top of the yarn gathering support 4 of the spinning machine protrudes to form a baffle 44, so as to limit the outer side of the mesh belt 5. Finally, the mesh belt 5 is stably on the yarn gathering support 4 of the spinning machine.

[0056] The mesh belt 5 is a nylon mesh belt with certain elasticity and can be sleeved on the yarn gathering support 4 of the spinning machine; the bottom of the mesh belt 5 is supported by a support 6; the two side areas of the strong poly-spinning component of the present utility model are open areas, which facilitates the removal of the mesh belt 5 and the replacement with a new mesh belt 5.

[0057] The dust suction nozzle 7 has a flat nozzle 71, which is close to the yarn outlet side mesh surface of the mesh belt 5; the inside of the dust suction nozzle 7 is a dust suction cavity 72, which is in communication with the cavity 2; thus, negative pressure can be generated at the opening part of the nozzle 71 to remove dust and clean the surface of the mesh belt 5.

[0058] The strong poly-spinning component of the present utility model is applied to a spinning machine, which enables the spinning machine to be converted into a strong poly-spinning machine, as Figures 6 - 9 shown; the docking air duct 1 of the strong poly-spinning component is connected to the dust suction air duct 91 inside the spinning machine, and the cavity 2 and other components of the strong poly-spinning component are located outside. In particular, the part of the mesh belt 5 located on the top of the yarn gathering support 4 of the spinning machine is in contact with the rubber roller 8 on the spinning machine, and the contact point is on the front side in the yarn outlet direction of the yarn gathering nozzle 41, close to the front side edge of the top of the yarn gathering support 4 of the spinning machine, as Figure 9As shown; the rubber roller 8 is driven by the roller to rotate, and then drives the mesh belt 5 to move through friction;

[0059] The roving strip A is pre-drafted by the roller apron 95 and then enters the top apron 96 for further drafting and then enters the rubber roller 8. While the rubber roller 8 drafts and applies pressure, the outer circumferential chamfer of the rubber roller 8 is used to frictionally drive the mesh belt 5. At the same time, the fibers are strongly gathered under the adsorption of the strong gathering spinning component, and the suction nozzle 7 also sucks the mesh belt 5 at the same time.

[0060] The dust suction air duct 91 and the strong gathering spinning component are interconnected by a suction pipe 92.

[0061] After the fibers are twisted by the spindle after strong gathering spinning, they are wound and formed to complete the operation of the fine spinning process.

[0062] The rubber roller 8 is located on the upper outer side and can be easily replaced. The outer ring of the rubber roller 8 is made of rubber and has elasticity, so it can be better pressed against the upper surface of the mesh belt 5 to form pressure and generate the frictional force to drive the mesh belt 5 to move.

[0063] The diameter of the rubber roller 8 is preferably 50mm ± 10mm.

[0064] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
